The strong intrinsic Coulomb interactions of Frenkel excitons in crystalline carbon nitride(CCN) greatly limits their dissociation into electrons and holes, resulting in unsatisfactory charges separation and photocatalytic efficiency. Herein, we propose a strategy to facilitate excitons dissociation by molecular regulation induced built-in electric field(BIEF). The electron-rich pyrimidine-ring into CCN changes the charge density distribution over heptazine-rings to induce BIEF between melon chains. Such BIEF is sufficient to overcome the considerable exciton binding energy(EBE) and reduce it from 38.4 meV to 16.4 meV,increasing the excitons dissociation efficiency(EDE) from 21.5% to 51.9%. Our results establish a strategy to facilitate excitons dissociation through molecular regulation induced BIEF, targeting the intrinsic high EBE and low EDE of polymer photocatalysts.

福建省作为中国的产茶大省,快速准确地获取茶园的空间分布对于福建省的农业经济发展以及生态环境建设具有重大的决策意义。本研究在GEE云平台调用与处理Sentinel-1(S1)雷达数据和Sentinel-2(S2)多光谱数据,结合地形数据从中提取光谱特征、纹理特征、地形特征等98个特征,利用递归消除支持向量机算法(SVM_RFE)对特征变量进行筛选,共设计4种特征组合方案,通过支持向量机分类器(SVM)进行茶园提取,并分别对4种分类方案进行精度评价,获得了福建省2020年10 m分辨率茶园空间分布数据。在此基础上,利用GEE云平台获取福建省2000–2020年植被干扰信息,以2020年茶园提取结果掩膜剔除2000–2015年影像中非茶园区域,得到2000–2020年每隔5年的福建省10 m分辨率茶园空间分布数据集。本数据集利用样本点对重点产茶县市进行人工验证,结果表明:2020年茶园提取精度在92%以上,利用干扰数据剔除法获得的2000年、2005年、2010年、2015年茶园提取精度均在80%以上。提取茶园精度较高,可为有关部门进行茶园管理提供支持。

我国水资源短缺,提升工业用水效率能够有效缓解水资源压力。针对现有工业用水计划中历史法和定额法的不足,通过探索不同时效因子组合对计划用水核定的影响,引入规模因子反映用水户的用水需求变化,采用动态标杆-定额限制法确定事务性、成效性因子赋值,提出年计划-季调节的动态管理模式,构建计划用水动态核定方法。案例分析结果表明:某用水户实际用水占核定计划用水的93.0%,经过季调节优化后,该比例提升至99.1%。该方法不仅克服了传统方法中的“滞后效应”和“鞭打快牛”的缺陷,还能够有效盘活计划用水与实际用水的差额,使工业用水分配合理化,实现了水资源在工业用水方面的高效利用。
